Secure, flexible and tamper proof

Liberty 1P is a meter for smart prepayment and managed credit applications. The meter maintains its own energy account and supports multi-rate time of use or slab tariffs. It has a social non-disconnection facility (friendly credit) which prevents disconnection during the night or on public holidays. The meter displays actual and historical information on consumption and cost of consumption. This allows consumers to see how much energy they are using and how much it costs. In addition the meter displays credit remaining and can estimate on demand how long the remaining credit will last based on the current rate of consumption. The meter and its associated system has built in features to counter fraudulent customers and reduce revenue losses.
